[0067] Hereinafter, specific embodiments of the present invention will be described in more detail with reference to the accompanying drawings. These drawings show representative embodiments of the present invention and are not intended to limit the present invention.

[0068] The utility model provides a floating water driving device and a vehicle. The vehicle 100 with the floating water driving device can be considered as an amphibious vehicle.

[0069] The following will refer to Figures 1 to 7 The floating water drive device 120 and the vehicle 100 of the illustrated embodiment will be described in detail.

[0070] According to the utility model, the floating drive device 120 may include a rotating arm 121, a paddle wheel assembly 122 and a second driving member 123. The rotating arm 121 has a first end 121a and a second end 121b spaced along its own length direction D1. The first end 121a and the second end 121b here can be understood as the two ends of the rotating arm 121 along its own length direction D1. The rotating arm 121 is rotatably arranged around the first axis AX1 located at the first end 121a to change the position of the second end 121b in the vertical direction D2. The first axis AX1 intersects the length direction D1 and the vertical direction D2. The paddle wheel assembly 122 is arranged at the second end 121b of the rotating arm 121 to rotate around the first axis AX1 with the second end 121b to the storage position and the working position. The paddle wheel assembly 122 includes a first driving member 124 and a propeller 122e. The first driving member 124 is connected to the second end 121b of the rotating arm 121 and is driven to the propeller 122e so that the propeller 122e rotates around the second axis AX2. The second axis AX2 is parallel to the first axis AX1. When the floating drive device 120 is applied to the vehicle, the paddle wheel assembly 122 located in the storage position is higher in the vertical direction D2 than the paddle wheel assembly 122 located in the working position. The paddle wheel assembly 122 located in the working position and rotating around the second axis AX2 in the liquid is suitable for forming a thrust. The liquid here refers to water in particular. The second driving member 123 is driven to the first end 121a of the rotating arm 121 to drive the rotating arm 121 to rotate around the first axis AX1.

[0071] According to the floating driving device 120 of the utility model, the second driving member 123 drives the rotating arm 121 to rotate, so that the paddle wheel assembly 122 moves to the storage position and the working position. When the floating driving device 120 is applied to the vehicle 100, when the paddle wheel assembly 122 is located at the storage position, the paddle wheel assembly 122 can prevent the ground clearance of the vehicle 100 from being reduced, thereby reducing the impact on the vehicle 100 traveling on land; when the paddle wheel assembly 122 is located at the working position, the propeller 122e is driven to rotate by the first driving member 124, and the rotating propeller 122e can form a driving force in the liquid, thereby helping the vehicle 100 to move in the wading environment. The propeller 122e can rotate around the second axis AX2 under the drive of the first driving member 124. When the vehicle 100 needs to be driven by floating, the second driving member 123 drives the rotating arm 121 to rotate to the working position, and the rotating propeller 122e can stir the water flow to form a reaction force to drive the vehicle 100 to travel.

[0072] See also Figures 1 to 5 For example, the impeller assembly 122 may include a hub 122a, a rim 122b, and a blade 122c. The rim 122b is sleeved outside the hub 122a and is arranged concentrically with the hub 122a. The blade 122c is connected between the rim 122b and the hub 122a to form a spoke. The blade 122c and the hub 122a together form a propeller 122e (e.g., Figure 5 The propeller 122e is configured to generate a thrust force along the axial direction of the hub 122a when rotating in the liquid. Here, a wheel and a propeller are integrated together, so that the wheel has the functions of driving on land and in a wading environment.

[0073] Continue reading Figures 1 to 5 In addition, the paddle wheel assembly 122 may also include a tire 122d. The tire 122d is sleeved on the outside of the rim 122b and is arranged concentrically with the rim 122b. The paddle wheel assembly 122 here can be used as a spare tire when the first drive member 124 is removed. When the spare tire is connected to the first drive member 124, it can be used as a propeller 122e to enable the vehicle 100 to travel in a wading environment. At the same time, the first drive member 124 also provides a mounting structure for installing a spare tire, which is conducive to reducing the occupancy of the trunk space corresponding to the spare tire. Moreover, when the first drive member 124 is removed and the paddle wheel assembly 122 is used as a spare tire, it can also replace a damaged wheel to support the vehicle 100 to travel on land.

[0074] Optionally, the structure composed of the propeller 122e, the rim 122b and the tire can be a spare tire of the vehicle.

[0075] See also Figures 1 to 7In addition, the floating drive device 120 may further include a reduction assembly 125. The reduction assembly 125 may include a power input end 125a and a power output end 125b. The transmission ratio of the power input end 125a and the power output end 125b of the reduction assembly 125 is less than 1. The power input end 125a is transmission-connected to the second drive member 123. The power output end 125b is transmission-connected to the first end 121a of the rotating arm 121 to transmit power between the second drive member 123 and the rotating arm 121. By arranging the reduction assembly 125 between the second drive member 123 and the rotating arm 121, the purpose of increasing the torque can be achieved by reducing the speed reduction, so that the rotating arm 121 is driven more stably to drive the first drive member 124 and the impeller to rotate.

[0076] For example, the speed reduction assembly 125 may be a gear transmission assembly. As a speed reduction implementation, the gear transmission assembly is relatively easy to implement and helps to ensure transmission accuracy.

[0077] exist Figure 6 and Figure 7 In the example shown, three sets of gears are used as the gear transmission assembly for transmission. The three sets of gears are arranged in sequence on the power transmission path, and the driven wheel of the first set of gears is coaxial with the driving wheel of the second set of gears. The driving wheel of one set of gears is connected to the second driving member 123, and the driven wheel of the other set of gears is coaxial with the transmission shaft 126 below.

[0078] See also Figures 1 to 5 For example, the paddle wheel assembly 122 is located on one side of the rotating arm 121 along a direction parallel to the second axis AX2. The floating drive device 120 may further include a transmission shaft 126. One end of the transmission shaft 126 is connected to the first end 121a of the rotating arm 121. The other end of the transmission shaft 126 protrudes from the other side of the rotating arm 121 along a direction parallel to the first axis AX1 and is transmission-connected to the second drive member 123. Here, the paddle wheel assembly 122 and the second drive member 123 are arranged on both sides of the rotating arm 121 along a direction parallel to the second axis AX2, so that the paddle wheel assembly 122 and the second drive member 123 can be prevented from interfering with each other.

[0079] See also Figure 3 , Figure 4 , Figure 6 as well as Figure 7In addition, the floating drive device 120 may further include a housing 127 and a locking assembly 130. The transmission shaft 126 is rotatably arranged relative to the housing 127. The locking assembly 130 may include a first locking member 131 and a second locking member 132. The first locking member 131 is fixed to the transmission shaft 126 to rotate with the transmission shaft 126. The second locking member 132 is movably connected to the housing 127 in a locked position and an unlocked position. The second locking member 132 located in the locked position is engaged with the first locking member 131 to prevent the transmission shaft 126 from rotating. The second locking member 132 located in the unlocked position is disengaged from the first locking member 131 to allow the transmission shaft 126 to rotate. Here, by providing the locking assembly 130, it is possible to lock the rotating arm 121 after the rotating arm 121 rotates to a corresponding position, so that the rotating arm 121 can be maintained at a corresponding position.

[0080] exist Figure 3 , Figure 4 , Figure 6 as well as Figure 7 In the example shown, the first locking member 131 is a ratchet. The second locking member 132 is a pawl. The pawl includes a root end and a tip end. The root end and the tip end are the two ends of the pawl. The root end of the pawl is rotatably connected to the housing 127 around a third axis AX3 parallel to the first axis AX1. When the pawl rotates to make the tip end of the pawl snap into the groove of the ratchet, it means that the pawl as the second locking member 132 is in the locked position. When the pawl rotates to make the tip end of the pawl disengage from the ratchet, it means that the pawl as the second locking member 132 is in the unlocked position.

[0081] See also Figure 7 In addition, the floating drive device 120 may further include a locking adjustment component 150. The locking adjustment component 150 is adapted to adjust the second locking member 132 to move between a locked position and an unlocked position. By providing the locking adjustment component 150, it is convenient for the user to change the position of the second locking member 132 as needed.

[0082] Continue reading Figure 7 For example, the locking adjustment assembly 150 may include an elastic member (not shown) and an adjustment member 151. The elastic member is connected to the pawl. The elastic member is suitable for applying an elastic force to the pawl so that the pawl rotates toward the unlocking position. The adjustment member 151 is movably disposed on the housing 127. The adjustment member 151 is disposed corresponding to the tip of the pawl along the radial direction of the ratchet. The adjustment member 151 is suitable for applying a force toward the ratchet to the tip of the pawl during the movement, so that the pawl rotates toward the locking position.

[0083] Optionally, the elastic member is a torsion spring. The torsion spring is suitable for providing a torsional force to the pawl so that the pawl moves toward the unlocking position around the third axis AX3.

[0084] See also Figure 7 For example, the adjusting member 151 can be movably arranged relative to the housing 127 in a direction parallel to the third axis AX3. The adjusting member 151 can be a rod-shaped or columnar structure. The end of the rod-shaped structure can be set into a cone or other variable diameter shape to form a guide surface on the periphery of the end of the rod. Take the example that the distance between the guide surface and the axis of the transmission shaft 126 decreases in the direction close to the impeller assembly 122. When the adjusting member 151 moves in a direction parallel to the third axis AX3 in a direction away from the impeller assembly 122, the adjusting member 151 can apply a force toward the ratchet to the tip of the pawl through the guide surface, so that the pawl can move toward the locked position. When the adjusting member 151 moves in a direction parallel to the third axis AX3 in a direction close to the impeller assembly 122, the pawl can automatically rotate toward the unlocked position under the action of the elastic force of the elastic member.

[0085] When the floating drive device 120 according to the utility model is in use, the second drive member 123 provides the power required by the transmission shaft 126 and the rotating arm 121. The reduction assembly 125 converts the high-speed and low-torque power output by the second drive member 123 into low-speed and high-torque power. The transmission shaft 126 outputs the power of the reduction assembly 125 after deceleration and torque increase to the rotating arm 121. The ratchet can be locked after the rotating arm 121 rotates to the target angle according to the conditions such as the posture of the whole vehicle, so that the rotating arm 121 is maintained in a better posture and the impeller assembly 122 is maintained in a better position. The bottom shell part 127a and the cover part 127b provide a mounting structure for the reduction assembly 125 and other components and are easy to be installed on the back door 110 of the vehicle 100.

[0086] See also Figure 6 and Figure 7 For example, the housing 127 may include a bottom shell portion 127a and a cover portion 127b. The bottom shell portion 127a and the cover portion 127b are connected. The second drive member 123, the reduction assembly 125 and the transmission shaft 126 are all mounted on the bottom shell portion 127a. The cover portion 127b at least covers the reduction assembly 125. The cover portion 127b and the bottom shell portion 127a may be connected by fasteners such as bolts. In the installed state of the vehicle 100, the bottom shell portion 127a is connected to the vehicle body. After removing the cover portion 127b, the user can repair or maintain the relevant components.

[0087] See also Figures 1 to 7 For example, the second driving member 123 and the first driving member 124 can both be electric motors. As the electric motor of the first driving member 124, one of the motor housing 127 and the output shaft is connected to the rotating arm 121, and the other of the motor housing 127 and the output shaft is connected to the hub 122a of the impeller assembly 122.

[0088] Optionally, the second driving member 123 can be a motor. The motor shaft of the motor can be coaxial with the first axis AX1. The motor shaft of the motor can be non-coaxial with the first axis AX1. In the case where the motor shaft of the motor is not coaxial with the first axis AX1, a transmission structure can be provided between the motor and the rotating arm 121 to achieve power transmission.

[0089] Optionally, the first driving member 124 can be another motor. The motor shaft of the other motor can be coaxial with the second axis AX2. The motor shaft of the other motor can be non-coaxial with the first axis AX1. In the case where the motor shaft of the other motor is non-coaxial with the first axis AX1, a transmission structure can be provided between the other motor and the propeller 122e to achieve power transmission.

[0090] According to the floating drive device 120 of the utility model, the spare tire and the propeller are integrated together to form a paddle wheel assembly 122. In order to realize that the vehicle 100 can travel on land and on water, the related art generally adopts the solution of adding an additional water propeller. The floating drive device 120 of the utility model cleverly utilizes the spare tire, which is a structure that is used for land travel but not commonly used, and combines it with a propeller with a water travel function to form a paddle wheel assembly 122. In this way, it not only realizes water travel, but also solves the problem that the related art affects land travel due to the increase of the demand for water travel. The floating drive device 120 has a compact structure. When the vehicle 100 is traveling on land, the paddle wheel assembly 122 is located in the storage position. At this time, the ground clearance and appearance of the vehicle 100 and the general vehicle 100 are basically the same, so that the vehicle 100 does not affect the driving of the vehicle 100 on land. When the vehicle 100 floats on the water, it can prevent the spare tire integrated with the propeller from sinking into the water, providing a driving force for moving forward or backward. Moreover, when the paddle wheel assembly 122 is placed underwater, since the tire 122d is hollow and buoyant, the spare tire can play a role similar to a buoyancy device to increase the buoyancy of the entire vehicle in the water.

[0091] The utility model also provides a vehicle 100. The vehicle 100 may include the above-mentioned floating driving device 120. The paddle wheel assembly 122 is a spare tire of the vehicle 100. The paddle wheel assembly 122 is arranged at the rear of the vehicle 100.

[0092] According to the vehicle 100 of the utility model, by applying the above-mentioned floating drive device 120, the vehicle 100 can adapt to the needs of driving on land when the paddle wheel assembly 122 is in the storage position, and can adapt to the needs of moving in a wading environment with the help of the rotation of the propeller 122e when the paddle wheel assembly 122 is in the working position.

[0093] See also Figures 1 to 3For example, the vehicle 100 may include a back door 110. The back door 110 here may be understood as a trunk door or a luggage compartment door of the vehicle 100. The floating drive device 120 may include a reduction assembly 125, a transmission shaft 126, and a rotating arm 121. The transmission shaft 126 runs through the back door 110. The reduction assembly 125 is connected to the side of the back door 110 facing the inside of the vehicle 100. The rotating arm 121 is located on the side of the back door 110 facing the outside and is spaced apart from the back door 110. The first axis AX1 is parallel to the front-rear direction D3 of the vehicle 100 when the back door 110 is in a closed state. When the second driving member 123 drives the rotating arm 121 to rotate so that the impeller assembly 122 rotates to the working position, the propeller 122e is driven to rotate by the first driving member 124, so that the vehicle 100 can move in a wading environment. When the first driving member 124 drives the rotating arm 121 to rotate so that the paddle wheel assembly 122 rotates to the storage position, the vehicle 100 can be driven on land, and the paddle wheel assembly 122 can be prevented from reducing the ground clearance of the vehicle 100, thereby reducing or avoiding the impact on the vehicle 100 driving on land.

[0094] According to the vehicle 100 of the utility model, by integrating the floating drive device 120, the spare tire and the back door 110, the first drive member 124 can also be hidden by utilizing the hollow space on one side of the rim 122b of the spare tire along the axial direction. The first drive member 124 is connected to the spare tire through a connecting structure. The rotating arm 121 replaces the bracket that originally only serves to fix the spare tire. At the same time, the housing 127, the deceleration assembly 125 and the second drive member 123 and other components are hidden on the side of the back door 110 facing the inside of the vehicle 100. This makes the entire design space structure compact, does not occupy too much extra space, does not affect the vehicle 100 on land and does not affect the appearance of the vehicle 100.

[0095] Compared with the related art, the vehicle 100 of the present invention has the following advantages and differences:

[0096] (1) The present invention designs the spokes of the spare tire to be similar to the blades 122c of a propeller, so that the spare tire has the function of a propeller. When the vehicle 100 is traveling on water, the first driving member 124 drives the spare tire to rotate and provides a water thrust force, thereby driving the vehicle 100 to travel on water. When the vehicle 100 is traveling on land, the spare tire can be moved to a higher position to avoid reducing the ground clearance of the vehicle 100. In addition, the spare tire can be removed to replace the damaged wheel of the vehicle 100 for driving.

[0097] (2) The utility model can change the position of the paddle wheel assembly 122 by driving the rotating arm 121 to rotate by the second driving member 123. When the vehicle 100 is traveling on the water, the second driving member 123 rotates the rotating arm 121 by 180° so that the paddle wheel assembly 122 moves to the working position. Then the first driving member 124 is started to drive the propeller 122e to rotate. The rotating propeller 122e stirs the water flow to form a reaction force, thereby driving the vehicle 100 to travel on the water. When the vehicle 100 travels from the water to the land, the second driving member 123 rotates the rotating arm 121 by 180° so that the paddle wheel assembly 122 moves to the storage position. At this time, it is ensured that the paddle wheel assembly 122 is not close to the ground and does not affect the vehicle 100 traveling on land. When the spare tire needs to be removed, the paddle wheel assembly 122 can be rotated by the second driving member 123 at a certain angle, such as 90°, so as to leave more space suitable for operation for removing the spare tire.

[0098] (3) When the vehicle 100 is traveling on water, the paddle wheel assembly 122 including the spare tire is rotated to a working position. The repositionable spare tire does not increase the design space and can increase the buoyancy of the entire vehicle in water.

[0099] To sum up, compared with the related art, the utility model uses the original design space suitable for the vehicle 100 to drive on land to achieve water driving without increasing the occupied space and without affecting the vehicle 100 to drive on land. It has the advantages of highly integrated functions, compact space design, and easy disassembly and assembly.

[0100] The working mode of the vehicle 100 of the present utility model is as follows:

[0101] When the user drives the vehicle 100 into a river or a sea, the user can input a command to the floating drive device 120. The second drive member 123 starts after receiving the command and outputs power to the reduction assembly 125. The reduction assembly 125 reduces the speed and torque of the power output by the second drive member 123 and transmits the power to the transmission shaft 126. The transmission shaft 126 drives the rotating arm 121 to rotate 180° around the first axis AX1, driving the paddle wheel assembly 122 including the spare tire to rotate from the first axis AX1 to the second axis AX2. Figure 1 Rotate to the storage position shown Figure 2 The pawl is then rotated around the third axis AX3 to the locking position, so that the tip of the pawl is inserted into the tooth groove of the ratchet wheel to lock the transmission shaft 126, thereby fixing the posture of the rotating arm 121, so that the paddle wheel assembly 122 remains in the working position. At this time, if the first driving member 124 is started, the propeller 122e of the spare tire can be driven to rotate around the second axis AX2, and the propeller 122e stirs the water flow to generate a reaction force, thereby providing a driving force for the vehicle 100 to move forward or backward, thereby driving the vehicle 100 forward or backward.

[0102] When the user is in a river or sea and does not want the vehicle 100 to move forward or backward, the user can input another instruction to the floating drive device 120 to control the first drive member 124. The first drive member 124 stops rotating according to the other instruction. At this time, the spare tire including the propeller 122e and other structures is immersed in the water. Since the spare tire usually stores gas, it can increase the buoyancy of the vehicle 100 and effectively prevent the vehicle 100 from sinking.

[0103] When the user leaves the river or the sea, the user can input another command to control the second driving member 123. The second driving member 123 is activated according to the command, and then outputs power to the reduction assembly 125. The reduction assembly 125 reduces the power output by the second driving member 123 and increases the torque and transmits it to the transmission shaft 126. The transmission shaft 126 drives the rotating arm 121 to rotate 180° around the first axis AX1, driving the spare tire 306 from the first axis AX1 to the second axis AX2. Figure 2 The working position shown is rotated to Figure 1 The first driving member 124 is integrated with the spare tire, and the first driving member 124 can be placed in the concave structure on one side of the rim 122b, making the structure more compact, so as not to occupy too much space of the vehicle 100. In this way, the appearance of the vehicle 100 of the present invention is basically the same as that of a general vehicle 100, reducing the impact on the aesthetics of the vehicle 100 when driving on land.

[0104] When the vehicle 100 encounters a tire blowout or needs to remove the spare tire, the second driving member 123 can be started to drive the rotating arm 121 of the water driving device to rotate, so that the first driving member 124 and the impeller assembly 122 can rotate as shown in FIG. Figure 1 The storage position shown is adjusted to a certain angle, thereby leaving the required space for disassembling the spare tire. At this time, use a disassembly tool to disassemble the second drive member 123, thereby separate the first drive member 124 and the spare tire, and replace the damaged wheel with the spare tire.

[0105] In summary, according to the vehicle 100 of the utility model, by using the floating drive device 120 integrating the spare tire and the propeller, and hiding the second drive member 123, the deceleration assembly 125 and the housing 127 on the side of the back door 110 of the vehicle 100 facing the inside of the vehicle 100, the structure is compact, does not occupy too much extra space of the vehicle 100, and the appearance is basically the same as that of a general vehicle 100. In this way, the vehicle 100 does not affect driving on land, and has the function of floating on water.
